LED light source is becoming more mature and portable projector first profit

With the continuous development of the projection market, now small and portable has become the future direction of the projector. But for now, most of the mainstream portable projector on the market are still staying at about 2 kg. This is mainly because the projector light source and heat dissipation problem has not been well resolved.

Understand the projector knows, currently on the market most of the projector light source mainly comes from the light bulb, because of high heat dissipation lamp, and projector and the smaller the more unfavorable for machine cooling, the cooling effect is not good it will directly affect the service life of the bulb; also because the volume of the lamp itself relatively large, so to be more compact and portable is a certain degree of difficulty. However, with the appearance of LED light source, it is a good solution to this series of problems. LED is a light emitting diode, which is also known as the fourth generation lighting source or green light source. Compared with the traditional lighting source, LED light source is characterized by high luminous efficiency, low power consumption and very low heat emission. Therefore, the use of LED light source, not only a good solution to solve the problem of heat dissipation projector, and because of its low power consumption, but also effective energy saving. With the LED technology matures, there have been more and more portable projector products using LED light source, such as Samsung, MITSUBISHI, Toshiba, and many micro projector products like this are frequently exposed by LED light source. However, the LED light source projector is also facing a very serious problem, which is the lack of brightness, which to some extent also restricts its development. But for these pockets, and even can be called micro cast products, they are not very high brightness requirements for the product, and LED light source can also meet the needs of these projectors. In addition, because the LED light source is small, and it has a number of display technology advantages, particularly suitable for the development of portable projector, and even some micro investment such as the original, the projector can truly achieve portability and free projection dream. At the same time, the LED light source has a very obvious advantage is long, its service life can be up to 60 thousand to 100 thousand hours, 10 times longer than traditional light source life, but also solves the problem of the life of the projector.
